The size field of the svmon -G output shows the total amount of real memory on the system.

The following svmon -G fields show how the memory is being used:

-The free field displays the number of free memory frames

-The work field in the in use row displays the number of memory frames containing working segment pages The pers field in the in use row displays the number of memory frames containing persistent segment pages

-The clnt field in the in use row displays the number of memory frames containing client segment pages

These four fields add up to the total real memory. (i.e = work_inuse+per_inuse+clnt_inuse+free = real)
